<div dir="ltr">Thanks Christophe, I really appreciate it. I am heading out of town, but may get a chance to test it tomorrow. If not, it will be a week before I am back to work. I will also look through the other node ordering. I think all of the quadratic volumetric elements have different node orders. If you already tested the tetrahedron, but not the others then I will send you the line of code to reorder the second order prism (C3D15). I think the others would be fine.<div>
<br></div><div>If there is anyone on the CalculiX group who gets a chance to download the nightly Gmsh build and test its exporting of the quadratic hex (C3D20), please post if it works for you. Thanks!</div></div><div class="gmail_extra">

Looking at th 2.8.2 source, line 245 of the header file Geo/MHexahedron.h needs to reorder the local node numbers. There are examples in the lines above and below. The local node coordinates are in the Gmsh and CCX docs. Double check it, but this should be correct (these are the comments from my translator):<br>

</div>Hi Jeff - I've committed a patch with your renumbering: can you give it a try?<br>
<br>
Also, please let us know if your see other renumbering problems in the Abaqus export: we have not tested this anything other than forst order triangles/tets...<br>
<br>
Thanks,<br>
<br>
Christophe<br>
